The P0872 error code indicates a situation where the Transmission Fluid Pressure Sensor/Switch C is reading a low voltage. This could affect the transmission's ability to shift properly, which may lead to performance issues. Drivers may notice unusual behavior in their vehicle’s transmission, including slipping gears or harsh shifting.

What are the symptoms of the P0872 code?

Drivers experiencing a P0872 code may notice:

• Delayed or harsh shifting of the transmission.
• An illuminated check engine light on the dashboard.
• Transmission slipping or failing to engage properly.
• Possible stalling or loss of power during acceleration.

What causes the P0872 code?

Common causes of the P0872 fault code include:

• Faulty Transmission Fluid Pressure Sensor.
• Damaged or corroded wiring and connectors in the pressure sensor circuit.
• Low transmission fluid levels due to leaks.
• Failed transmission control module (TCM).

How to fix P0872?

To resolve the P0872 code, consider the following steps:

• Inspect the Transmission Fluid Pressure Sensor and replace it if faulty.
• Check the associated wiring and connectors for damage, corrosion, or loose connections.
• Ensure that the transmission fluid is at the correct level, and top it off if necessary.
• If the issue persists, further diagnostics may be needed to test the transmission control module.
